Sonny told me that they now dock there on a recent post, which is great. One of the fishing charters that I had looked into asked if we were docking in Playa del Carmen or Cozumel?
The ships list's it as "Cozumel"???

How can I tell which port out of three on Cozumel we will be docking at?? This list only goes ahead a couple of months? In Feb it shows the Enchantment at TMM International Peir? Should I call RCCL or will that ship always dock at that pier? You do get many different answers when you call them????

I don't think you can know for sure. The EOS and RCI Ships have been docking at the International Pier but things can change, you might not even go to Cozumel. I have been on a cruises with medical emergency's or bad weather that have completely changed their itinerary.
